Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

EPA issues final rule regulating “forever chemicals”
The Environmental Protection Agency announced that it will issue a rule aimed at limiting public exposure to per- and polyfluoroalkyl substances (PFAS). The final rule will designate two widely used PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund.
According to the EPA, both PFOA and PFOS meet the statutory criteria for designation as hazardous substances.

The China lead-based research reactor (CLEAR-I) with 10 MW(thermal) will be built for the research of the accelerator-driven subcritical system (ADS) and lead-cooled fast reactor technology. Compared with other reactors, ADS has a spallation target placed in the reactor core center, which affects the refueling motion in the vessel. It is difficult to reach the fuel assemblies near the proton beam tube through the common vertical refueling gripper. In this technical note, a new cantilever-type and internal grasping gripper with defined refueling process was designed to handle all assemblies in CLEAR-I. The static and kinematics analyses of the gripper were carried out by ANSYS Workbench and MATLAB considering the influence of working in air and liquid metal. The structural and kinematic simulation results show that the design of the gripper is feasible for CLEAR-I. It provides an advanced refueling solution for the technical validation of ADS.
